Which of the following would the nurse recognize as ACE inhibitors? SELECT ALL THAT APPLY

Captopril

Lisinopril

Atenolol

Labetalol

Ramipril

Answer and Explanation

Correct Answer : A,B,E

Choice A reason: Captopril is an ACE inhibitor, which means it blocks the enzyme that converts angiotensin I to angiotensin II, a hormone that constricts blood vessels and raises blood pressure. Captopril is used to treat high blood pressure, heart failure, diabetic kidney disease, and some types of heart attack. ¹

Choice B reason: Lisinopril is also an ACE inhibitor, with similar effects and uses as captopril. Lisinopril may be preferred over captopril because it has a longer duration of action and fewer side effects. ²

Choice C reason: Atenolol is not an ACE inhibitor, but a beta blocker, which means it blocks the receptors for adrenaline and noradrenaline, hormones that increase heart rate and blood pressure. Atenolol is used to treat high blood pressure, angina, irregular heartbeat, and prevent heart attack and stroke. ³

Choice D reason: Labetalol is also not an ACE inhibitor, but a combination of alpha and beta blocker, which means it blocks both the receptors for adrenaline and noradrenaline, and the receptors for angiotensin II. Labetalol is used to treat high blood pressure, especially in pregnancy and hypertensive emergencies.

Choice E reason: Ramipril is another ACE inhibitor, with similar effects and uses as captopril and lisinopril. Ramipril may have additional benefits in preventing cardiovascular events and kidney damage in high-risk patients..

Correct Answer is C

Explanation

Choice A reason: This is incorrect because labetalol is a safe and effective medication for treating hypertension in pregnancy. Labetalol is a beta-blocker that lowers blood pressure by reducing the heart rate and the force of contraction. It does not affect the blood flow to the placenta or the fetus.

Choice B reason: This is incorrect because labetalol is not contraindicated for smokers. However, smoking is a risk factor for cardiovascular disease and should be discouraged by the nurse. Smoking can increase blood pressure, heart rate, and the risk of blood clots.

Choice C reason: This is correct because labetalol is contraindicated for clients with a history of uncontrolled asthma. Labetalol is a non-selective beta-blocker that can block the beta-2 receptors in the lungs and cause bronchoconstriction. This can worsen asthma symptoms and trigger an asthma attack.

Choice D reason: This is incorrect because labetalol is a suitable medication for clients who had a myocardial infarction. Labetalol can prevent further damage to the heart muscle by reducing the oxygen demand and the workload of the heart. It can also prevent arrhythmias and angina.

Correct Answer is ["83"]

Explanation

To calculate the IV flow rate in drops per minute, we can use the following formula:

IV flow rate (gtt/min) = (Volume to be infused in mL drop factor) / Time in minutes

Given:

Volume to be infused = 250 mL

Drop factor = 10 gtt/mL

Time = 30 minutes

Using the formula:

IV flow rate = (250 mL 10 gtt/mL) / 30 min

IV flow rate ≈ (2500 gtt) / 30 min

IV flow rate ≈ 83.33 gtt/min

Rounding to the nearest whole number, the nurse should set the manual IV flow rate to deliver 83 gtt/min.
